Sensitivity measures how often a test correctly identifies those who have a strep infection. A test with high sensitivity will not lead to many false-negative outcomes and will be able to detect almost everyone who has the disease.
Specificity measures how often a test correctly identifies those who don’t have a strep infection. A test with high specificity will correctly exclude individuals who don’t have the disease and will not generate many false-positive results.
Our strep testing is highly accurate when it comes to detecting group A strep, exhibiting 98.5% sensitivity and 93.4% specificity.
